Application ned May 24, v1905. semi No'. 262.031.

Alabama, have invented new and useful Im provemerits in'RegisteringMechanism for Calculating-Machines, of which the following` isaspeciiication.

My .invention relates to registering mechanism for calculating orsimilar machines,

such as I have describedin a pending application, Serial No.217,851,1iled by me the 23dl dayof J uly,'1904, wherein a plurality ofrockshafts are directly operated by` rows of keys and registering-dials'are operatively con- `nected to the shafts and moved thereby incorrespondence with the movements imparted to the shafts by the keys,each keyl acting to rock its lrespective shaft in propor tiontoitsvalue.

In machines of this character the uniformity of key resistance to thetouch of the operator is most important for rapidvoperation, which Iconsider of prime importance.V

In my pendin application I haveshown various devices or maintainingthekey resistance .in moving the shafts to different degrees substantiallyuniform, and with this object in view I have adapted the registeringmechanism constituting my present invention land a division of my saidpending application to perform its'carrying or transferring fromidial todial in a gradual manner, so that the key resistance will not beincreased as a shaft is rocked tovmove its dial from 9 to 0 and carry lto the dial of higher degree.

Where this gradual 'carrying or transferring action obtains, it visimportant 'to provide I against confusion in reading the totals on theseveral dials which would arise from the tendency of the carryingoperation to move the dials of higher degree almost a completeregistering step before the actual :point of registry is reached, thusmoving their indicated numeral partly out of the `field of vision andbrin ing the succeeding numeral of higherl va ue artlyninto the/field.This is particularly o ijectionable in calculating-machines, wiere everyprecaution should be taken against possibility of mistake by theoperator in reading the registered items or totals.v To obviate this, Iprovide each dial vupon which the carrying operationtakes ef- 4fect witha movable shieldor plate which has a sight-opening through Which one ofthe nu merals on thedial4 is vislble and is adapted to y l move with itsrespective dial during the gradthe proper indicating-numeral in viewuntil the point of registry forthe carrying operation 1s reached, whenthe plate Shifts its pothrough its sight-opening a numeral of higherdegree` Thus though the carrying operation is gradual so far as theoperating mechanism is concerned it is practically instann taneous sofar' as it concerns the indicating` or totaling.

It is a further object of my invention to adapt these dial-shields toserveas a portion ofthe transfer mechanism,l means being pro vided toimpart to themthe gradual carrying movement from the dial of lowerdegree, which each shield in turn imparts to its respective dial, untilthe reached, when the shie d releases the dial and returns to itsinitial position, the dial remaining stationary. f

A still further object of the invention is to rovide a novel form ofresetting mechanism by which all of the registering or totaling dialsmay be quickly reset to Zero position, and, further, to so arrange themechanism that the use cf the resetting device is op tional with theuser, it being possible to restore and quickly reset the dials to a zeroposition by means of the keys. f With these and other objects in view,as will more fully hereinafter appear, the invention consists of thenovel construction and arrangement of parts hereinafterfully dcscribed,illustratedin the accompanying drawings, and particularly pointed out inthe appended claims, -it being understood that various changes in theform, proportions, size, and minor details of the structure may be mafiewithout departing from the spirit or 'sacriiicing any of theadvantagesof the invention. 4

Similar reference-numerals refer to' similar parts' through out theydrawings. The registering-mechanism which forms the subject-matter ofthis application constitutes a part only of the. operating partsembody#V ing calculating-machine, Which 'being fully described 1n myaforesaid pending 'applicationmay be here briefly referred to ascomprising acasing 1, formed preferably of metal and provided 'withtransparent. panels of glass, such as 2, through which the opefat ingparts may be inspected. The top 'of the casing is formed by a pluralityof metal strips 3, extending from the glass 2, Where they are supportedon a transverse r{viiilirtition tto the e abuttingside rear wallof thecasing. edges of these strips are recessed' to'provide .openings throughwhich the shanks 5 of the The keys' are arranged in as,

keys pass. man rows of nine each as the capacity of the `mac ine mayrequire, the first row being for units, the secondvfor tens, the thirdfor hundreds, &c. yThe keys of each row are provided with finger-pieces6, which are succes# sively numbered from l to 9, beginnin at the fron'tof the machine. The Shanks of the keys are formed of metal bars providedwith shoulders 7, arranged at progressively- 'decreasing ydistances fromthe finger-pieces of each-row from front to rear, so that thesuccessive'keys of a Arow'have strokes of.

varying length. In the case of the keys numbered 9 these shoulders maybe dispensed with, when the finger-piece will serve lportioned to itsnumerical value.

as 4a sto to limit the downstroke of the key. From t iis arrangement itfollows that each key will have a stroke whose length is pro- 1slongitudinally slotted4 at 8 and provided at its lower end with a"circular plate 9, whichv enters a cylindrical casing 10, secured to thebottom of the casing and serving as a guid'e'for the lower end of thekeys. 4Coiled springs 11 lwithin these casings engage plates'9 and actto return the keys to their initial position.

- Corresponding with each row of keys is a rockerrSl-iaftialZ, journaledin bearin s in plates'13 l"a-n'd 14, disposed., .respective y, at pointsnear thefront and rear walls of the l casing and'further supportel atintermediate points by cross-bars 15. 'The bearing portions of the shaftare reduced to prevent its 'longitudinal displacement. .Each shaft 12 isoperatively connected with the keys of av row by means of ninerocker-arms 16,- each of which asses through the slot in a key- 'shankan is adapted to be engaged b an antifriction-roller- 17, journaled1nthes ank when the key is depressed and moved to rocki E a'ch sh anky'the-shaft 12. The am xtsntof the staaf-S travel being preferablyfifty-four degrees, it follows' that'the extent of thelmovement for eachunits value will besix degrees'. Each rocker-shaft' is actedupon by aspring 18 through coperating levers 19 and 20 (more fullyoe'scribed inthe companion application), to'return it to lits initial ositionl assoon as the 4depressed key wbic operated it -has been` released andreturned by its spring 11. -The upward movement of the keys is stopped'by small pins 21, extending through the key'- lshanks-and'adapted toengage lthe under side of the Atop of the casing.' The movements-'oftherock-shafts 12 are transmitted tothe registering mechanism by. meansof arms 22,- keyed to the front end of the shafts andk carrying dogs'23,which-engage ratchet-Wheels 24, mounted on short shafts 25. These shaftsare journaled in the partition'4 and bearing-plates 13 and carrygear-wheels 26, disposed near thepartition 4. Gear-'Wheels 27 mountedonv shafts 28,l mesh with gears 26, these counter-shafts being journaledinthe partitions or plates 4 and 29', which' are preferably angled attheir lower ends and bolted to the bottom of the casing. Thesecounter-shafts also carry the units-registering dial 30, and tens,hundreds, &c., registering dials 31, which are keyed thereon anddisposed between the two bearing-plates. The transmission-gearing isdesigned to transmit to each dial a rotary m0vement corresponding tothat imparted to its respective shaft 12 by the depression of a key,which movement-will advance the. dial the number of points representedby the operat ing-key.

IOC

Though the mechanism hereinbefore dewheels or disks having preferablytwo setsof vdigits from 0 to 9 arranged in rotationaround'their-peripheries. 'lhe units-dial will be operated by the firstrow 'of keys on the right through their respective shaft 12 andtransmission-gears, the tens-dial by thesecond row of keys and theirshaft 12,' the hundreds-dial bythe third row of keys, Sac. Each of thedials carries a ratchet-wheel 32, having a number of teethcorrespondingl to the number of digits O'n the dial-t. e., twenty. Sring-pressed pawls 33, fulcrumed to the p ate 29, engage eachratchet-wheel and" act to prevent a reverse movement ofthe dials. Eachdial is further provided,with a cam-sur- Maese face this surface beingpreferably formed by the periphery of a cam-disk .34, which issecured toor formed integral with the dial. In

' accordance with the present construction this disk will have twocam-surfaces, one for each set of digits, which terminate in shoulders35, -dlsposedopposite the digit of each set.- Each cam-surface commencesat the termination. of a left -of their centers and -length so thattheir free ends project beyond on'a gradual arc until it terminates atthe other shoulder. A lever 36, pivoted to the plate `4 at a point aboveand to the right of each cam-disk, rests upon the adjacent disk,

so that with each complete rotation of the .'15

latter the lever will be twice raised by the action of thejcam-surfacesandv 'lowered b dropping oil' the shoulders. 5 The levers pre point wellto the erably engage the disk ata the-arc circumscribedby thecamfshoulders.4

Each of the dials 31are covy 'ered by segmental shields 40, preferably 3 loosely onregistering-dials and.

formed of" light sheet metal and fulcrumed the shafts 28. These shieldsserve to cover the upper periphery of the lare provided with asight-openings 30, which expose only one of the digits-on each of thedialsat a time. An

farm 41 ex-tends downwardly'at an angle from. each of the shields andcarries at its lower end a spring-pressed pawl 42, which is adaptedr toengage the teeth of a ratchetwheel 32and1mpart to this wheel and its;l

'Theshields do not the levers A36. rest but 45V which projects v .gageswiththe lever 36, which rests upon the j ried by the project over thccam-disks 34, upon which the ulcr'umed shields 40 are each providedwith. a pin or lu 43, over the'cam-disk an encam-diskof the adjacentdial of lower degree.

that the shields will movements ofthe levers,

The carryingv or transferring operation is shoulder and increases are ofsulicient j necessarily vrespond to three dials tothe right will berotated by the operating mechanisnn so that they expose, through thesight-openings 39, the numerals 594. When this is the case, the shields,cams,- and levers for these dials will occupy the. positions indicatedinFigs.. 3 and 4. lt will be noted that the units-dial .cam has lifted itslever 36 nearly one-half of its travel, whichmovement of the lever hasbeen improjects and engages with parted to the shield 4() of thetens-dial, which has been thus rocked on its axis from its initialposition indicated by a dotted line. The engagement of the pawl A42,carried bythe shi'eldearm 41,- has moved the tens-dial forwardapproximately half a step, as may be noted from the position of the pawl33 withl lregard to the ratchet-teeth. The operation of the tens-'dialto expose the digit `9 leaves thisdial on the .point of transferring orcarrying to the hundreds-dial. Thus it will be noted that the tens-lever36 vis nearly atthe where any further movement. ofthe tens-dial willlift it and throw the hundreds-shield for-v ward sufficiently to causethe pawl 42 to drop behind the ratchet-'tooth of the hundreds# dial, onthe' edge of which it is shown resting.l As this loccurs the tens-leverdrops behind top of the cam-surface and in a position i Ico shoulder3.5, when spring 4.4 swings the hundreds-shield 40 to t next digit ofhigher being held against a right by its engagement with pawl 33. Thiscarryingoperation ispositive, requires only a gradual application ofpower, maintains the exposed digits in'fullview until the point fororder, .thehundreds-'dial e right andexposes the similar movement to theregistering the digit carried forward and exposing a higher numeral-isreached, and acts independently lof the v.operating mechanism, i

it being noted that the forward -movement imparted toa dial by itsshield is transmitted.,

through the'meshing gears 26`and 27, tothe 'ratchet-wheel 24, whichmoves" forward, bringing other teeth into engagement with vpawl 23. Theratchet-wheel 24 will be preferably of considerable diameter andprovided with Va large number of'very fine teeth, the purpose being, tohave as great anumber o f teeth as possible subtended by the. arci ofmovement of the ratchet-wheel in registering .one digit. The effect ofthis is to minimize wheel 24, dueto the carrying action, so that thelost motion between thearm 22 and the it will be less am theayaiowabiefor-.the digit exposed through t e sight-opening of its.dial-Shield. l

rWith the mechanism thus far described the y f depression of any keyin/'anyvertical column Will-'eifect rotative movement of the disk atthefoot ofthat column to an extent dependent on the-'digit-keydepressed, and, further. the, transfer lfrom disk to disk may be made ioso thatY the*successively-increasing totals will be at all times visiblethrough the glass panel .5,fthe arrangement of the rocking shields beingsuchv that the sight-openings in the latter will remainaboveareviously-exposed digit yl'mtilftheshield is al owed to move overthe nexty digit. l

To'the forward end of each' of the dialshafts 28, which project throughthe plate 29, lis' secured. a cross-bar 48, disposed in a plane :zeparallel with the dial and'provided at or near its ends Withprojectingpins 49, which are adapted to' be engaged by the resetting me ch--anism;hereinafter described and effect -the :rapid restoration ofallthe dials to initialo l:z 5 fzero, position.

Theresetting mechanism is disposed at "the front endofl the casing andcomprises a swinging .plate or support 50, having lugs 51 at. itsopposite lower corners, which are piv- 3o `voted by pins 52 to the sidewalls of the casing.

When thc arms 59 are inposition to engage `one of the pins 49, their arc of travel l with thegears 57 is suliicient to pick up each of'thebars 48 and move the dialsthrough shafts 28 'to zero position. The plate 50' is further providedwith bearings for the reception of a shaft 60,'Which extends outwardthrough a vertically-disposed slot 61 in the 6o front wall of thecasing. To the outer end fof this shaft is secured a disk 62, carrying avlpin 63, which projects through an arcuate slot 64 in a cam-disk 65,which is loosely fulcrumcd on the outer end of the shaft 60.

y65 iT-hef-.cam-disk rests on a small -shelf 66, se-

seaeea cured to the front offthecasing, and is adapted to be operatedbyaghandlc 67, which under .normal conditions rests against a pin 68,-

projecting from the casing. To reset the dials to initial position, thecrank 67 is moved upward, which -causes the cam-surface ,of

vlatter with the pin 63, so that the disk 62,

which is keyed to the Shaft, is not moved.. After thishowever, the leftend of the slot will engage the pin, and as the movement of the levercontinues until stopped by the pin 69 4the disk 62 will be turned andits movement transmitted, through shaft 60, to a gear 70, connected tothe rear end ofthe shaft and disposed beyond the plate '50. This gearmeshes with a short rack formed on the bottom of the rack-bar 56, andthus imparts sidewisc movement-to the rackebar. The movement of therack-bar is transferred to all of the mutilated gears 57, which swingtheir arms 59 through an are sufficient to cngage one or the other ofall the pins 49 and restore the dials to zero position by the time thecrank-lever -67 has completed its movement by engaging stop 69. As thecrank is moved -to the left a reverse -operation takes place, whichmoves the rack-bar to the left and restores the gears 57 to the positionindicated in Fig. 5 and permits the spring 53 to swing the plate 5() outof its voperative position.

The provision of two sets of digits on the dials necessitates the use oftwo pins 49 and, as before stated, two cam-shoulders 35. lt will beobvious, however, that a greater or less number of sets of digits may beused, in which case the said parts will be increased and decreasedaccordingly.
